Thanks for posting. It's hard to tell what you have while your hardware is still installed. I am also not sure what your dimensions are. That said, your shoe resembles our 15-199. Start by looking it over and seeing how well it matches your original. Please also see our Series 160 and Series 165 coil springs.
